#change UBT will check for API version of all UnrealHeaderTool binaries to detect partial syncs
#change Added BuildHostPlatform class for runtime platform abstraction

- Adds experimental super-fast C++ outdated file checking
- This feature is turned off for now as we continue to test and improve it
- You can try it out by enabling "bUseExperimentalFastDependencyScan" option in your BuildConfiguration.xml
- Here is the basic idea:
- We no longer exhaustively scan all includes and build up a big graph every invocation
- Instead, source files whose build products are missing have their includes scanned asynchronously while being compiled
- The flat list of dependent includes for every outdated C++ is saved into a new cache file ("FlatCPPIncludes.bin")
- On the next run, we quickly load that up and "just know" which files to check timestamps on to determine what is out of date
- Lots of "@todo fastubt" comments were added to UnrealBuildTool for potential performance optimizations and further improvements on this feature.
UnrealBuildTool: Determination of which modules have UObjects is now faster
- We now cache which modules have UObjects and load those for the next session
UnrealBuildTool: Module "shared" precompiled header determination is now much faster
- We no longer scan all C++ includes for a module to figure out which "shared" PCH to use
- Instead, we use the module dependencies specified in the module's *.Build.cs file
- For example, if your module depends on "Engine" and "UnrealEd", we choose "UnrealEd"'s shared PCH
Other UBT optimizations:
- Reduced calls to string formatting functions when setting up API definitions for all modules
- Added new performance diagnostics when bPrintPerformanceInfo is enabled in BuildConfiguration.xml
- We no longer check for "external" headers when scanning includes (this code didn't work at all)
- Optimized CleanDirectorySeparators() utility function to avoid string copies
Fixed UnrealBuildTool not saving DependencyCache under a platform-named folder

#TTP 342328 (HTML5: Packaging Blueprint projects fails)
- A compiler generated file was missing from the manifest, fixed
- clean up - instead of calling static functions, call virtual function on tool chain, move platform specific code to derived tool chains.

- Only compile Metal if the engine is being compiled
- Fixed compiling PhysX for programs (removed Cooking lib for all configurations) in Android and IOS
- Deleted the PhysXCookingDEBUG.a lib for IOS and Android

- Integrated IPhonePackager code directly into IOS Automation (this is not 100% working yet, it's a work-in-progress). Original IPP still in same place untouched
- Added a return code to RunLocalProcess
- Added IPhonePackager UAT script that will pass along params to the internal IPP code (RunUAT IPhonePackager -cmd="<ipp commandline here>" [-nocompile])

- XSD driven IntelliSense
- defaults read from code (default XML file will be regenerated on UBT startup if is different than it should be)
- configurable classes/fields have to be now annotated with XmlConfig and XmlConfigField attributes

* Create intermediate directories to use for unzipping so we don't pollute directories not expecthing these temp files
* Skip frameworks not part of the target being considered
* Cleanup

* Work in progress, works with RPC utility, local mac support incoming
* Changed AdditionalPublicFrameworks from storing just string, to storing the frame work name, zip name, and bundled asset name that needs to be copied
* We also now store the module that added this framework, so we can derive the module project path, etc when we need it for when we create intermediate directories
